Thomas Brown (October 24, 1785 – August 24, 1867) was an American politician who served as Florida's second Governor from 1849 to 1853.

Thomas Brown was born in Westmoreland County, Virginia, United States, home to George Washington, James Monroe, and others.

Brown served in the War of 1812, and subsequently became chief clerk of the post office at Richmond.

East Florida Seminary in Ocala was one of the first schools to utilize this funding, but it soon closed due to the Civil War.

Brown was inspired by the discovery of the rich muck lands of the Lake Okeechobee area and encouraged cattlemen and farmers, protected by the Florida militia, to enter the region.
